Ukuphela kokumangalisa okuPhezulu, ngomthi
Cwangcisa 3, Ngokhuni, Big 4 * 4 * 4.5cm, Phakathi 3 * 3 * 3.5cm, Encinci 2.5 * 2.5 * 3cm
"I-Flip top" ingumlinganiso ophezulu kunye nesiphelo esikhulu kunye nesincinci. Xa le gyro ijikeleza emhlabeni inentloko enkulu ezantsi, ayinakushukuma ijikeleze icala nkqo njenge gyro yesiqhelo, kodwa inokuphinda iye phantsi iyonke kwaye iqhubeke nokujikeleza kunye nentloko yayo encinci emhlabeni. Iflip ephezulu ibizwa ngegama layo, kwaye itsala umdla koososayensi ababini abakhulu.
Utitshala uShu Yousheng uwukhankanyile lo mzekelo kwincwadi yakhe ethi "Mechanics". Makhe ndithethe ngayo ngenye indlela. Isizathu kufuneka sifane.
Xa iibhuleki zebhasi ngequbuliso, abakhweli baya kungxama ukuya phambili okanye nokuwa; Ukuba ubaleka esitratweni, ukuba ngempazamo ukhubeke kwinyathelo, uya kungxama uye phambili okanye uwe. Isizathu sobabini siyafana. Unyawo lwakho lume, kodwa umzimba wakho uqhubekile nokuqhubela phambili ngenxa ye-inertia, ke uwe. Inokuchazwa kwakhona nge-torque, iziko lomzimba lobunzima lijikeleza ngokuhambelana nonyawo.
Umphezulu unokuwa phantsi. Umphezulu ojikelezayo ohamba ngokuthe tye ngaxeshanye, ukuba ubetha umqobo, ungawelwa sisiphithiphithi. Ukuba iimeko zichanekile, inokuqhubeka nokujikeleza emva kokuwa kwempazamo.
